I don’t know how many people stay up all night playing with their phones after turning off the lights?
Recently, a post-90s girl in Jinan, Shandong always felt that something was flying in front of her eyes, so she went to the hospital for treatment. After examination, it was found that the girl had a retinal tear in her eye, and accompanied by Ruptured blood vessels in the eye.
Only after consultation, I learned that this girl worked during the day for two consecutive days and watched dramas all night at night. Excessive use of the eyes for a long time can easily cause eyeball damage, especially patients with high myopia are more prone to retinal tears.
What kind of eye disease is a retinal tear?
The so-called retinal tear, we have to talk about the lower vitreous first.
The vitreous is a gelatinous substance in the eyeball that supports the retina. If there is a posterior vitreous detachment, the retina will be gradually pulled.
On this basis, if there is thinning of the retina at this time, retinal tears may occur.
For middle-aged and elderly people and myopic patients, posterior vitreous detachment is prone to occur, especially in patients with high myopia, which is not only prone to vitreous liquefaction and posterior detachment, but even easier lattice degeneration occurs.
It is worth mentioning that retinal tears are not always symptomatic< /p>
The most obvious symptom is the appearance of floating objects in front of the eyes. These floating objects will repeatedly appear in the center of the field of vision, and at the same time, they will continue to increase. There may be a flash of less than 1 second in the later stage.
Most retinal tears are asymptomatic and are only discovered through eye examinations.
Lying down and playing with the phone for a long time can damage the eyes irreversibly
For most of the modern population, the behavior of not leaving the mobile phone occurs every day. If you lie down and play with your phone for a long time before going to bed, your body will undergo some very big changes.
Lying on your phone for a long time before going to bed, what changes will your body have?
First, impaired vision
When lying down and playing with a mobile phone, blood will flow into the eyes, causing the conjunctival blood vessels to become congested to varying degrees.
The palpebral conjunctiva will also have mild papillary hyperplasia, which will form some follicles, which will cause flushing or crusting and moistening of the corners of the eyes.
Over time, it will cause some chronic inflammatory lesions, easy to suffer from conjunctivitis, and also induce other eye diseases, resulting in worse and worse vision.
If the screen of the mobile phone is too bright and looking at the mobile phone in a dark environment for a long time, it may cause video terminal syndrome, dry eyes, sore eyes, red eyes > and other symptoms, severe may cause inflammation of the cornea or conjunctiva, which in turn damages the lens and retina.
Second, frequent cervical pain
Lying down for a long time and playing with mobile phones will change the physiological curvature of the cervical spine.
Once this change occurs for a long time, the cervical vertebrae will experience soreness, numbness and discomfort, and due to excessive strain on the cervical vertebrae, the probability of suffering from cervical spondylosis will relatively increase.
As a result, patients often experience discomfort such as numbness, pain and stiffness in the cervical spine in daily life.
Third, frequent dizziness
Many people will experience a series of head discomforts, such as dizziness or dizziness, and even nausea after lying down and playing with their mobile phones for a while before going to bed.
The reasons for this are:
One is due to the physiological curvature of the cervical spine, resulting in nerve root compression and poor carotid blood flow< /strong>.
The second is that due to lying down and playing with mobile phones for a long time, the blood flow rate will become very slow, resulting in a decrease in the amount of blood supplied to the brain, resulting in insufficient blood supply to the brain, which will cause dizziness , dizziness, or discomfort such as dizziness, nausea.
Fourth, decreased sleep quality
Once you lie down and play with your phone for a long time, the brain will always be in a state of tension and excitement, which will affect sleep and cause insomnia.
Many people turn off the lights when they lie down and play with their mobile phones before going to bed. The blue light emitted by mobile phones will inhibit the secretion of melatonin and also affect sleep, resulting in a decrease in sleep quality. .
Whether lying down or sitting, it is the right way to reduce the use of mobile phones
Use of mobile phones, computers and other electronic products for a long time, excessive use of eyes, easy to make eyes tired and dry. Both adults and children should learn to use the eyes correctly and combine work and rest.
It is recommended to use the eyes continuously for 1 hour and rest for about 5-10 minutes to reduce eye fatigue.
Use your eyes as much as possible in a well-lit environment. Do not lie down with your eyes. When using mobile phones and computers, you should sit upright and keep the distance between the screen and your eyes at 50-60 cm.
But having said so much, how many people are really willing to put down their mobile phones and go to bed earlier?
